[測試] 4K IOPS衝破127,000，Intel SSD 320 G3 120GB x 6 Raid 0 詳細測試，附G3詳細規格說明

延期又延期的X25-M G3，加上Crucial RealSSD C400又遲遲未有貨，已經擾亂左我的升級計劃，直到今星期見到Intel G3正式出貨，唯有入Intel G3頂住先。

Intel G3已正式改名為Intel SSD 320，但包裝盒和G2並沒有大分別，甚至連所用的Controller也一樣，SSD型號結尾仍採用G3為Product Code。

測試環境：Intel Core i5 2400 on ASUS H67 SATA 6Gb/s Port

先來就是單隻Intel SSD 320 120GB的HD Tune Read測試，最高連續讀取速度為269MB/s







HD Tune Write測試，最高連續寫入速度為137MB/s









AS SSD Benchmark @ Microsoft Windows AHCI Driver，Windows內建的AHCI Driver效能偏低，4K讀/寫速度不及Intel RST AHCI Driver





AS SSD Benchmark @ Intel RST 10.1 AHCI Driver，4K讀/寫速度比Windows內建的AHCI Driver高出太約10%

=================================================================

測試到這裡大家可能已經發現了一個問題，就是拿Intel H67 On-Board Raid來接G3 120GB x 4 Raid 0時，H67的

效能表現已顯得有點力不從心，當到了G3 120GB x 5 Raid 0時情況就更加明顯，已不能把G3 120GB x 5 Raid 0該

有的效能完全釋放出來，而且在超過700MB/s開始的高速讀寫時CPU的使用率亦越來越高，當讀取速度達1GB/s時CPU

的使用率更高達接近30%，但以On-Board Raid來說H67 PCH的整體表現仍是較上一代的ICH10R來得好一點。

=================================================================

Intel H67上的G3 120GB x 6 Raid 0這部份的測試已完成，因受限於Intel H67 On-Board RAID晶片的限制，並未能完全釋放出120GB x 6 Raid 0該有的全部效能，但在4K-64Thrd多工模式下4K IOPS仍能衝破127,000，對On-Board RAID晶片來說已經不能再有什麼好挑剔的了
